## This libcap (for proftpd) is originally from libcap-0.104,
## at ftp://linux.kernel.org/pub/libs/security/linux-privs.
## The interface in the orginally library is slightly buggy, and
## because capabilities are new to linux 2.1, the api may change
## before 2.0 comes out. If this library stops working, please contact
## proftpd-l@evcom.net.
